This has changed, findaspect now has the array options expanded to 20 chars:
Syntax: int findaspect(real start, real end, char p1[16], char asp[11], char option[20], real angle, real lon, real lat, real zone);
See it's help.
The extra options are:
9 exit after first find ingress
10 search void of course.
The rest of the options array is for future use.
